The reaction of potassium tetrachloroplatinate with [Ph3PCH2C(O)Me]Cl in DMSO synthesized the platinum complex [Ph3PCH2C(O)Me]+[PtCl3(dmso-S)]-, the structure of which was established by X-ray analysis. Cation tetrahedral configuration is hardly distorted: CPC valence angles vary in the range of 105.75(13)°–112.99(15)°, P-C bond lengths do not differ much from each other (P-CPh 1.788(3)-1.797(3) Å, P-CAlk 1.805(3) Å). In the square-planar anion the dimethyl sulfoxide molecule is coordinated to the central sulfur atom (Pt-S 2.2083(8) Å). Trans-angles SPtCl (178.63(3)°) and ClPtCl (177.20(3)°) are close to 180°.References
